Pick the one that fits you best and is the most comfortable - they're pretty simiar. If you can get the Euromesh seat on either bike (Barcroft uses Bacchetta's Euromesh too) it will allow for more recline than the seat mesh. Other options in that format are the Volae Tour and the just-introduced Rans Enduro Sport.

Have you eliminated a Volae Century? In a small frame it fits riders with x-seams of 36” to 41” and is available with either carbon or mesh seat. They are so popular with shorter riders that Rolf has problems keeping the small frames in stock.
